The invention realizes the technical effects of double spiral grooves on the outer periphery of the flexible shaft and double knitting wool embedded under the premise of ensuring the normal use of the flexible shaft, remarkably relieves the friction between the flexible shaft and the inner wall of a pipeline on the periphery of the flexible shaft when the flexible shaft rotates at high speed, eliminates the noise and prolongs the service life of the whole flexible shaft to the maximum extent.
Description
Technical Field
The invention relates to a flexible shaft and a corresponding processing method thereof, in particular to a double-floss flexible shaft and a processing method thereof, belonging to the technical field of flexible shaft processing.
Background
The flexible shaft is a shaft with small rigidity, elasticity and free bending transmission, and is mainly used for connecting two shafts which are not on the same axis and in the same direction or have relative motion so as to transmit rotary motion and torque. In the field of automobiles or other mechanical devices, flexible shafts are often used to transmit torque for flexibly transmitting rotational motion to any location.
In order to ensure the safety of personnel during the rotation process of the flexible shaft, the flexible shaft is usually arranged in a relatively closed pipeline to rotate during the application process of the flexible shaft, and therefore, the flexible shaft inevitably rubs with the inner wall of the pipeline at the periphery of the flexible shaft during the rotation process to generate larger noise. In order to reduce noise, the prior art solution is to reserve a spiral groove when winding the outermost layer of steel wire of the flexible shaft, and then embed a knitting wool in the spiral groove to alleviate friction between the flexible shaft and the inner wall of the pipeline.
In the face of some special application scenes, a client needs to reserve two spiral grooves on a flexible shaft to embed two knitting wools. However, with the existing production process, only one spiral groove can be reserved and one knitting wool can be embedded in the processing process of the flexible shaft, and once two spiral grooves are reserved, the conditions of silk scattering and the like are easy to occur in the use process of the flexible shaft.
In summary, how to provide a brand new double-floss flexible shaft with two outer-layer-embedded floss and a processing method thereof becomes a problem to be solved urgently by the technical personnel in the field.
